Sia's appearance is especially exciting because of her famously elusive persona. She is rarely featured in her own music videos, and often uses her signature wigs to shield herself from invasive paparazzi and media. We hope she lets her guard down a bit with Corden in the car, and maybe even sheds the extra hair.

Earlier this week, Sia debuted a new remix to her song "Cheap Thrill," featuring verses from Sean Paul. We're looking forward to Corden taking on Paul's Jamaican accent. And, if we know Corden at all, there will absolutely be a twinning wig moment.
